Abstract
A method executed by a User Equipment (UE) supporting Multi-Radio Dual Connectivity (MR-DC) with a first cell group and a second cell group in a mobile communication system is provided. The UE configures a primary path to the first cell group and a secondary path to the second cell group for uplink transmissions in an MR-DC operation. The UE determines whether the primary path is inapplicable when performing the uplink transmissions on the primary path. The UE switches from the primary path to the secondary path to continue the uplink transmissions in response to the primary path being inapplicable.
